The topic of this sub-thread is NDB/DME frequency pairing, not NDB/DME collocation. 1) There is no doubt that VOR and DME can be collocated. 2) There is no doubt that there is frequency pairing for collocated VOR/DME. The pairing scheme for DME/VOR, DME/MLS, and DME/ILS/MLS are documented starting on page 3-100 of ICAO Annex 10 Volume 1 "Aeronautical Communications". 3) There is no doubt that NDB and DME can be collocated. 4) There is considerable doubt that any real-world ground station implements frequency pairing for NDB/DME. No evidence of such pairing has been adduced. 5) There is considerable doubt that any real-world cockpit instrument implements frequency pairing for NDB/DME. No evidence of such pairing has been adduced. If NDB/DME frequency pairing exists, perhaps somebody would be kind enough to tell us what the pairing scheme is, and/or give an example of a real-world instrument that implements such pairing. Otherwise we will continue to assume that the lack of any such pairing within FGFS is entirely realistic. ------------------------------------------------------------------------------ Let Crystal Reports handle the reporting - Free Crystal Reports 2008 30-Day trial.
